------- Additional Comments From pinskia at gcc dot gnu dot org  2005-07-02 01:40 -------
This looks more like a C++ front-end bug as the C produces:
        size    align
sa      8       4
sa.a    8       4
sb      12      4
sb.b    8       4

Fixed, it was not really an ABI bug after all, just alignof being implemented
different/wrong.

This is also an issue for the trunk:

        size    align
sa      8       4
sa.a    8       8
sb      12      4
